Running-Related Injuries in Recreational Runners: Prevalence, Anatomical Distribution, and Associated Physiological and Training Factors

Background: Running-related injuries are a common issue among recreational runners and may affect training continuity and long-term participation. However, injury-associated factors remain unclear due to methodological heterogeneity and reliance on self-reported data. Objective:...

Collision dynamics of false-vacuum oscillons

A bstract We study the collision dynamics of localized oscillons in two classes of (1 + 1)-dimensional scalar field theories with metastable false vacua, a normal class with a positive quartic self-interaction term and an inverted class with a negative quartic term. We construct...

Painful temporomandibular disorders, sleep bruxism, and anxiety symptoms in adolescents: a cross-sectional study

To analyze the association between painful temporomandibular disorders (TMD), sleep bruxism, and anxiety symptoms in adolescents. A cross-sectional study was conducted with 497 adolescents aged 14-19 years. Data were collected on sociodemographic characteristics, painful temporom...

Methodological Approaches for Ultrasound Assessment of Peripheral and Abdominal Muscle Thickness in Intensive Care: A Scoping Review and Proposed Reporting Framework

ABSTRACT Objective To map and synthesize methodological approaches used for ultrasound (US) assessment of peripheral (upper‐ and lower‐limb) and abdominal muscle thickness in critically ill patients, and to propose a preliminary Standard Operating Procedure (SOP) as a structured...

Effect of Nano-Silver Fluoride Containing 2000 ppm Silver Nanoparticles on the Microhardness and Color of Flowable Resin Composites: An In Vitro Pilot Study

Although the modification of resin composites with antimicrobial agents represents a viable alternative for biofilm inhibition, these changes may compromise the optical and mechanical properties of dental restorations. This in vitro pilot study evaluated the effect of incorporati...

Beyond binary urban-rural classifications: a continuous urbanicity gradient index

Abstract Traditional urban-rural dichotomies fail to capture the complexity of contemporary settlement patterns, constraining both scientific progress and policy applications in urbanization research. To address this gap, we introduce the Urbanicity Gradient Index (UGI), a contin...
